Abstract: A polycarbonate copolymer includes: a repeating unit represented by a formula (1) below; and a repeating unit represented by a formula (2) below, in which the repeating unit represented by the formula (1) is formed from a bischloroformate oligomer having an average number of monomer units n represented by a formula (100) below in a range from 0.1 to 1.3. In the formulae (100) and (1), Ar1 represents a group represented by a formula (3) below. In the formula (2), Ar2 represents a divalent aromatic group. In the formula (3) below, X1 represents a single bond or an oxygen atom. R11 each independently represents a methyl group or an ethyl group.

Abstract: A polycarbonate copolymer includes a repeating unit A represented by a formula (1) below, chain ends of the PC copolymer being terminated by a monovalent aromatic group or a monovalent fluorine-containing aliphatic group. In the above formula (1), R1 is a hydrogen atom or an alkyl group having 1 to 2 carbon atoms; an average repeating number n is in a range from 6 to 40 and L is an integer of 1 to 4; and when an aromatic ring is substituted by two or more of R1 (L≧2), the two or more of R1 are the same or different from each other.

Abstract translation: 在上式（1）中，R 1为氢原子或碳原子数1〜2的烷基。 平均重复数n在6至40的范围内，L是1至4的整数; 当芳环被R 2（L≥2）中的两个或更多个取代时，R1中的两个或更多个相同或不同。

Abstract: A bischloroformate composition is represented by a formula (1) below, contains a plurality of Ar components, and has an average number of monomer units (m1), which is calculated by an expression (Numerical Expression 1) below, ranging from 1.0 to 1.99. The plurality of Ar components are each independently Ar1 or Ar2. The plurality of Ar components include at least one Ar1 and at least one Ar2. Ar1 is a group represented by a formula (2) below. Ar2 is a group represented by a formula (3) below. A molar composition ratio represented by Ar1/(Ar1+Ar2) ranges from 45 mol % to 99 mol %. average number of monomer units (m1)=1+(Mav−M1)/M2 (Numerical Expression 1)
